A rare discovery of acute eosinophilic pneumonia associated with intensive cannabis use: Case report

This article explores the case of acute eosinophilic pneumonia (AEP) linked to heavy cannabis inhalation, amidst the rising prevalence of cannabis use globally. AEP, characterized by eosinophilic pulmonary infiltration, poses unique challenges due to its unclear pathogenesis. This case study involves a 20-year-old with recent intense cannabis use, presenting with acute chest pain, cough, and dyspnea. Diagnostic evaluation revealed bilateral interstitial syndrome on thoracic imaging and elevated blood eosinophilia. Additional investigation through bronchoalveolar lavage confirmed the diagnosis of AEP. The patient's condition rapidly improved with glucocorticoids, highlighting the significance of prompt treatment. This article underscores the importance of raising awareness among clinicians of the possibility of AEP following cannabis exposure as a diagnosis to consider, as timely diagnosis and intervention are paramount in averting potentially fatal outcomes.
